MODELLING PLATFORM WITH MULTIPLE REPRESENTATION FORMALISMS

摘要

Because every description formalism hasrnadvantages and disadvantages, a modellingrnplatform for ODE/DAE systems allowing severalrnformalisms would be required. MS1 is such arnprogram and is described in this paper. Itsrndevelopment will start in August 1991 andrnwill last three years.rnMS1 is based on an internal normalizedrnformalism that is actually a mere topologicalrnrepresentation of mathematical equation sets.rnWe call that formalism information networks .rnComputational causality is assigned afterrnsubsystem assembly and determines thernassignment form to be used in each specificrncase.rnThe program structure is designed sornthat it is easy to add a new input formalismrn-I.e. a description language - or a newrnoutput formalism -I.e. to address anotherrnsolver.
